Transaction management in triggers

You should not use transaction statements in triggers. A trigger is a special kind of stored procedure that takes effect when you issue a statement such as INSERT, DELETE, or UPDATE on a specified table or column. Triggers can be used to enforce referential integrity.

For example, assume that a certain condition within a trigger is not met and you want to execute a ROLLBACK. Instead of coding the ROLLBACK directly in the trigger, you should use RAISERROR and test for that particular return code in the DBMS-specific return code (SQLDBCode) property within the referenced transaction object.
